CAR-COUPLING.-

SPECIFICATION forn ing part of Letters Patent No 279,416, dated June 12, 18825.

Application filed'May 1, 18 83. 4 (No IllOllul To' all whom it may concern Be it known that I, HERMON MOON, of Grove City, in the county of Mercer and State of Pennsylvania, have invented certain new and usefulImprovements in Oar-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the'art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which .Figure 1 is a perspective view of my improved car-coupling mechanism detached from the cars. Fig. 2 is atop. view of the same. Fig. 3 is a side view, and Fig. 4 a longitudinal vertical section, of the same.

.Similar letters of reference indicate corresponding parts in all the figures.

, My invention has relation to automatic carcouplings; and it consists in the improved eon struction and combination of parts ofthesame, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicatesa plate adapted to be secured to the lower edge of the end of the car, and two parallel bars, 13, extend fromtheinner side of the same, and may be secured to the bottom of the car in any desired manner. 1?] ate A has three or more or less transverse slots, 0, one above the other, through which pass a correspond' ing number of flat bars, D, which are connected at their outer ends, forming head E, having its face rounded, and forming shoulders F on both sides of the bars. These bars are slotted longitudinally at G, near their inner ends, and a bolt, H, passing through and secured at both V ends in two cross-pieces, I, fastened to the up per and lower edges of the bars B, passes through the said slot-s, allowing the bars to slide upon the bolts. The rear. ends of the bars are connected by a yoke, J and a rod or bar, K, is hinged upon a bolt, L, passing through the bars and through the end of rod- K, and slides in a bearing, M, fastened between the bars 13.

Two yokes or plates, N, sliding between bars B, are fastened upon rod K, one on each side of bearing M, and springs 0, bearing against yokes N and bearing M, serve as cushions for the rod and the bars hinged to it when it is pushed in or drawn out.

' An upright lever, 1, is pivoted at its lower end upon the outer side of plate A to the side of the slots, and an arm, Q, is hinged to the same and to a bolt, R, passing through bars D immediately outside the slots, and the direction of the headed outer ends of the bars may be guided by the same.

The hereinbefoi'e-described portions of the coupling mechanism form the coupling for the end of one car, and the adjoining end of the other car is provided with a plate, S, fastened to the lower portion of the end of that car, and has two rearward-pointing flat bars, T, which are connected at their inner or rear ends by a cross-piece, U, and by two or more yokes or cross-pieces, between the plate and crosspiece U. The lower portion of plate S forms a large slot or aperture, \V, through which the outer ends of twolevers, X, project, which at their outer ends form hooks, adapted to catch and hold between them thehead E ofthe adjoining car. These levers are pivoted upon bolts- Y bet-ween two cross- )ieces Z which again are fastened at their middle to a longitudinal bar, (1-, which extends inward, sliding in bearings between the cross-pieces V. The outer end of this bar forms ahead, I), between the two levers, and the bar is slotted ,longitudiually at 0, immediately inside plate Sffor .the reception of a bolt, (7, iastened between the foremost pair of cross-pieces V.

.Two forward-pointing diverging springs, e,

are fastened to the sides of bar a, and bear with their outer ends against the inner ends of levers X, forcing them apart and consequently their outer "ends together. I

A bolt, f, is fastened between the inner pair of cross-pieces V and passes through a longitudinal slot, 9, near the inner end/of bar a, which is provided with a yoke, l1, the perforated ends of which slide upon two longitudinal rods, 17, fastened between the last pair of 5 cross-pieces V' and the cross-piece U, and having spiral springs j wrapped around them on both sides of yoke 71, bearing against that and the cross-pieces U and V, forming cushions for bar a. when it is either drawn out or pushed 1n.

Two levers, 7r, are pivoted near their inner IOO ends upon lugs I, projecting laterally from. the sides of bars 'I, and two bars, m, sliding transversely in slots at in the said bars, are hinged at their outer ends to the said levers, at the inner ends of the latter, while their inner ends are provided with projections or lugs 0, which bear against the outer edges of the inner ends of levers X, so that by drawing the outer ends of levers it: together the sliding bars m will be drawn out to the sides, drawing the inner ends of levers X together, opening their outer ends of lGVOlS I? to enter between the pointed or beveled ends of the jaws, forcing them apart, and be held between them when they are pressed together by their springs, and that the jaws may be opened, uncoupling the cars, by turning the hand wheel upon the vertical shaft. It will also be seen that by having the shouldered head of the one coupling made comparatively high. and formed by the ends.

of several bars sliding and rocking each in a separate slot in the front plate, it will fit into the coupling of cars of different height, and

the draw upon the head will be distributed between the several bars by their being connected by the shouldered head and at their inner end by a yoke, thus preventing any strain in a vertical direction interfering with the bars sliding freely horizontally. served that the sliding longitudinal bars serve as dra\v-bars, being cushioned by springs, when d fawn out, and as-bumpers, the shouldered head pushing against the fiat head between the jaws, and the longitudinal bars being also cushioned by springs, when pushedin.

To enable the coupling to be used in connection with cars having the link-and-pin coupling, the face of the shouldered head may be recessed and provided with a coupling-pin of the usual construction passing vertically through the end of the head, and a link may It will likewise be obbe made for the portion of the coupling having the shouldered jaws, which forms a shouldered head at one end, while the other end may be open and be fastened by a coupling pin in the usual manner.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a car-coupling of the described class, the combination of the plate A, having transverse slots 0 and parallel bars B, 'flat bars D, projecting through and sliding in the said slots, connected at their outer ends by the shouldered head E and at their inner ends by yoke J, and hinged to the spring-cushioned draw-bar K, as and for the purpose shown and set forth.

2. The combination of the shouldered head E, fastened to bars D, hinged tothe springcushioned draw-bar K, plate S, forming aperture \V at its lower portion, sliding springcushioned bar (I, having bumper-head I) and yokes Z at its outer end, hooked jaws or levers X, pivoted between the ends of yokes Z, diverging springs e, fastened to bar a and bearing against the the inner ends of levers X, transverse sliding bars m, having lugs 0 upon their inner ends, levers 7;, pivoted upon the sidesof the frame and hinged at their inner ends to bars 'm, and vertical shaft q, having chains or cords p and hand-wheel r, and j our-' naled upon plate S, as and for the purpose shown and set forth.

In a car-coupling, the combination of the mechanism consisting of plate A, parallel bars 13, flat bars D, forming head E, yoke J, sliding draw-bar K, having cushioning springs O, upright lever P, and hinged arm Q, with the mechanism consisting of plate S, bars '1, cross pieee'U, double cross-pieces V, jaws X, yokes Z, spring-cushioned draw-barn, having bumpei head t, flat diverging springs e, levers la, sliding transverse bars on, having lugs 0,

chains or cords p, and vertical shaft q, having hand-wheel r, as and for the purpose shown and set forth.

In testimony that I; claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
